Brain effects of high-intensity exercise on the dopamine system in individuals with Parkinson’s disease
Objective: We used PET imaging with 18F-FE-PE2I to quantify dopamine transporter availability and neuromelanin (NM)-MRI to measure the NM content in the substantia nigra (SN)…Longitudinal combined 11C UCB J and 18F FE PE2I PET imaging of presynaptic terminal loss in early Parkinson’s disease.
Objective: To longitudinally assess presynaptic terminal loss in vivo over a 2-year period in people with early Parkinson’s disease (PD). Background: Imaging tools that allow…Distinct amyloid-dependent patterns of nigral dopamine depletion in Lewy body diseases
Objective: To investigate the effect of amyloid on striatal 18F-FP-CIT uptake patterns in Lewy body disease (LBD), including Parkinson’s disease (PD) and dementia with Lewy…FDG-PET features of Lewy body dementia among patients with amnestic presentations typical for Alzheimer’s disease
Objective: To better understand the role of FDG-PET for identifying dementia with Lewy bodies (DLB) in the context of Alzheimer’s disease (AD)-like amnestic presentations, we…Multimodal assessment of nigrostriatal degeneration in de novo Parkinson’s disease
Objective: To study nigrostriatal changes with a multifactorial neuroimaging approach in order to further characterize early abnormalities in Parkinson’s Disease (PD). Background: Imaging techniques allow…Effect of exercise on brain metabolism and energetics in PD
Objective: To identity the effect of exercise on brain metabolism and energetics in PD using PET/MR imaging. Background: Aerobic exercise slows PD progression as reflected…Feasibility of artificial intelligence in predicting early phenotype conversion of REM Sleep Behavior Disorder
Objective: The goal of this study was to investigate the feasibility of deep learning in the prediction of disease conversion in RBD patients. Background: Rapid…Clinical correlates of Parkinson’s disease metabolic pattern: not only a diagnostic tool
Objective: To define and cross-validate the glucose metabolism abnormalities related to Parkinson's Disease (PD), and to analyze pattern relationship with clinical phenotype Background: In PD,…Characteristics of the amyloid beta networks in Parkinson’s disease patients: a PPMI study
Objective: The impact that amyloid beta (Aβ) accumulation in the brain has on the progression of Parkinson’s disease (PD) pathology is complex and poorly understood…Dissociated longitudinal evolution of limbic serotonergic and striatal dopaminergic and serotonergic pathology in apathetic and non-apathetic patients in early Parkinson’s disease
Objective: To investigate the longitudinal changes in striatal and extra-striatal dopaminergic and serotonergic innervation in apathetic and non-apathetic patients during the five years after the…
